Statistical Analysis in Forensic Science: Evidential Value of Multivariate Physicochemical Data

Synopsis

A Practical Guide For Determining The Evidential Value Of Physicochemical Data. Microtraces Of Various Materials (e.g. Glass, Paint, Fibres, And Petroleum Products) Are Routinely Subjected To Physicochemical Examination By Forensic Experts, Whose Role Is To Evaluate Such Physicochemical Data In The Context Of The Prosecution And Defence Propositions. Such Examinations Return Various Kinds Of Information, Including Quantitative Data. From The Forensic Point Of View, The Most Suitable Way To Evaluate Evidence Is The Likelihood Ratio. This Book Provides A Collection Of Recent Approaches To The Determination Of Likelihood Ratios And Describes Suitable Software, With Documentation And Examples Of Their Use In Practice. The Statistical Computing And Graphics Software Environment R, Pre-computed Bayesian Networks Using Hugin Researcher And A New Package, Calculator, For The Computation Of Likelihood Ratios Are All Explored.--publisher Info.
